Turning now to the drawings and more particularly FIGURES 1 through 3, there is illustrated a tool T comprising a stationary jaw member 1, movable jaw member 2, rail members 3, block member 4, a driving screw 5 and handle means 6. Each of rail members 3 has a channel 7 disposed therein, and, as can be discerned, each side of jaw member 1 is mateable with corresponding ends of rail members 3 with the jaw member and rail members being secured to each other. The other ends of rail members 3 are secured to block member 4 so that rail members 3 are disposed in a parallel manner.

Movable jaw member 2 has an extension 8 extending toward stationary jaw member 1. A projection 9 extends outwardly from each side of jaw member 2 and extension 8 and is mateable with a corresponding channel 7 in rail members 3 thereby allowing movable jaw member 2 to be movable relative to stationary jaw member 1. law members 1 and 2 have fiat surfaces 10, the flat surfaces of jaw member 1 resting on the tops of rail members 3 while the flat surfaces of jaw member 2 are ridable along the top surfaces of rail members 3.

Driving screw 5 has a smooth section 11 disposed in bore 12 in jaw member 1, a threaded section 13 mateable with threaded hole 14 in extension 8 in jaw member 2 and another smooth section 15 of less diameter than sections 11 and 13 having its end disposed in bore 16 of block member 4. A washer 17 is disposed between the front surface of jaw member 1 and hexagonal-shaped head 18. A circumferential groove 19 is disposed in driving screw 5 at the junction between sections 11 and 13, and a C-shaped washer member 26 is disposed within groove 19 in order to maintain driving screw 5 in position within jaw member 1 and block member 4 and to be movable relative thereto. A coil spring 21 surrounds section 15 and is disposed between the inside surface of block member 4 and threaded section 13. Coil spring 21 defines a drag means to supply friction to driving screw 5 so that a ratchet wrench 22, illustrated in FIGURE 8, can be effectively operated to rotate driving screw 5 and move movable jaw member 2 relative to stationary jaw member -1 during rotation thereof. Of course, jaw members 1 and 2 may be operatively connected to driving screw 5 so as to be movable relative to each other and to rail members 3.

Each jaw member has a circular-shaped channel 23 which is in communication with a similar shaped recess 24. The diameter of recesses 24 is larger than that of channels 23, and as can be discerned, recesses 24 face each other. Channels 23 and recesses 24 communicate with openings 23' in the upper surfaces of the jaw members. Locking members 25 are threadably mounted in the sides of jaw members 1 and 2 and they communicate with channels 23. Handle means 6 has one end threaded for engagement with nut members 26 secured to each rail member 3 so that a right-handed or left-handed person can use the tool.

Thus, FIGURES 1 through 3 illustrate the tool of the present invention which, upon ratchet wrench 22 or some other similar means being engaged on head 18 of driving 7 screw 5, causes movable jaw member 2 to be movable relative to stationary jaw member 1 when driving screw 5 is rotated in one direction or the other. In order to increase the speed of movement of movable jaw member 2 relative to stationary jaw member 1, the threads on threaded section 13 and in threaded hole 14 may be double or triple pitch threads. If desired, spring-biased locking members may be used in place of threaded locking members 25.

FIGURES 4 through 6 illustrate chuck means CM which is removably insertable'within channel 23 of either jaw member 1 or 2. Chuck means CM comprises a body member 27 having a tubular section 28 whose exterior diameter is mateable with channel 23. A stepped section 29 is located on body member 27 and is mateable with recess 24. A circumferential groove 30 is disposed in the exterior surface of tubular section 28. This groove receives the inner ends of locking members 25 when the chuck means is disposed within one of the jaw members in order to lock the chuck means in position therein as illustrated I in' FIGURE 8. Interior surface 31 of tubular section 28 merges with conical surface 32. Jaw members 33 are disposed against conical surface 32 as illustrated in FIGURE 5. Each jaw member has an arcuate shaped inner surface 34 and an arcuately inclined outer surface 35 mateable with conical surface 32. Hole 36 is disposed within each flat surface 37 of each jaw member, and hole 36 in flat surface 37 of one jaw member is in alignment with hole 36 in a flat surface of an adjacent jaw member. A coil spring 38 is disposed in aligned holes 36 between jaw members to provide spring bias therebetween.

As can be perceived from FIGURES 5 and 6, inner surfaces 34 of the jaw members define a circular configuration and the size thereof depends upon the position of the jaw members relative to conical surface 32 with coil springs 38 maintaining outer surfaces 35 into constant engagement with conical surface 32. Of course, the smallest diameter defined by inner surfaces 34 is the engagement between flat surfaces 37 of the jaw members.

A tubular member 39 is threadably engaged on body member 27 and includes an inturned section 40 having a threaded bore 41 coaxial with. the longitudinal axis of the chuck means. The inside surface of inturned section 40 engages the ends of jaw members 33 so as to position them relative to conical surface 32 depending upon the position of tubular member 39 relative to body member 27 in addition to retaining the jaw members within the chuck means. An aligning member 42 is threadably disposed in threaded bore 41 and has a bore 43 coaxial with the longitudinal axis of the chuck means. The exterior surface of the non-threaded part of aligning member 42 is provided with diametrical flat surfaces 44 which are engageable with a wrench means in order to tighten or remove the aligning member from tubular member 39. U-shaped recesses 45 are disposed in the exterior surfaces of body member 27 and tubular member 39 in order to be engaged by spanner wrench means to tighten and loosen the chuck means relative to a coaxial cable means on which an operation is to be formed which will be explained in greater detail hereinafter.

FIGURE 7 illustrates a flaring member 46 having a round section 47 mateable with channel 23 in one of the 4 jaw members. A circumferential groove 48 is disposed in the exterior surface of round section 47 and is engaged by the inner ends of locking members 25 to lock flaring member 46 within the jaw member. A flange 49 extends outwardly from one end of section of 47 and is mateable within recess 24. A flaring insert 50 is threadably disposed in section 47 in the end containing flange 49. A hollow projection 51 extends outwardly from the front surface of flaring insert 50 and has a beveled exterior surface 52. Flat surfaces 53 are diametrically disposed on the exterior surface of flaring insert 50 to enable a wrench means to be used to tighten or loosen the flaring insert relative to section 47. Flaring member 46 is shown in place in channel 23 of jaw member 1 in FIGURE 8.

In FIGURE 9 there is illustrated an expanding member 54 which is similar in every respect to that of flaring member 46 except that hollow projection 51 is aboutten times longer than that of projection 51. FIGURE 10 illustrates a pusher member 55 including a U-shaped body section 56 having an exterior part circular configuration for disposition within channels 23 of the jaw members. A groove 57 is disposed in the exterior surface of body section 56 for engagement by locking members 25. A U- shaped flange member 58 extends outwardly from one end of section 56 and is mateable with recesses 24 in the jaw members. An expander and drill member 59 is illustrated in FIGURE 11 and includes a body member 60 having a tubular extension 61 extending outwardly therefrom and a bore 62 in body member 60 in communication with tubular extension 61.

FIGURE 12 illustrates bolt 63 which is arcuate shaped in cross section. An extension 64 extends outwardly from the bottom surface of each end of bolt 63 and another extension 65 extends outwardly from the upper surface of bolt 63. A recess 66 is disposed in the upper surface of bolt 63 outwardly from one end of extension 65. A handle 67 extends outwardly from extension 65.

The type of coaxial cable to be terminated comprises a solid center conductor member surrounded by insulation means and an outer conductive sheath surrounding and snugly engaging the insulation means. In order to make a termination between coaxial cable means of the type disclosed in US. patent application Ser. No. 421, filed Dec. 29, 1964, the following procedure is set forth. The ends of two pieces of coaxial cable means C are cut so that they are perpendicular with respect to the longitudinal axis of the cable. The cut ends of the coaxial cable means are deburred on the interior of the outer conductive sheaths by a conventional deburring tool in order to remove any ragged edges that evolve during the cutting of the cable means. Expander and drill member 59 is applied to the center conductors of the coaxial cable means such that tubular extension 61 is shoved between the center conductor members and the insulation means; this moves the insulation means away from the center conductor member and allows the center conductor member to be drilled, if necessary, through bore 62.

If the center conductor members are drilled, a center contact member of the type illustrated in FIGURES 5 and 6 of Ser. No. 421,903 can be utilized to interconnect the center conductor members. If it is not desired to drill the center conductor members but to use a center contact member of the type illustrated in FIGURE 8 of Ser. No. 421,903, tubular extension 61 in moving the insulation means away from the center conductor member al-.

lows the center contact member to be readily disposed on the center conductor members to interconnect same. If

it is desired to apply threaded center contact members to the center conductor members such as illustrated in FIGURE 14 of US. patent application Ser. No. 3 5,7 7, filed Oct. 14, 1963, now US Patent No. 3, 7 granted Sept. 6, 1966, then the holes drilled into the center conductor members through bore 62 of the expander and drill member are threaded via conventional threading means in order to accommodate the threaded center contact members. Loading rings 68 having a frustoconical configuration are inserted onto the pieces of cable means with the ends having the smallest diameter being directed away from the ends of the cable means.

One of the cable means is inserted within chuck means CM and is secured therein with the end of the cable means in alignment with the outer end of aligning member 42. The chuck means along with the cable means secured therein is inserted in movable jaw member 2 with looking members 25 locking the chuck means in place therein. Flaring member 46 is placed within stationary jaw member 1 and locking members 25 lock the flaring member therein. Ratchet wrench 22 is applied to head 18 of driving screw 5 and movable jaw member 2 is moved toward stationary jaw member 1 until hollow projection 51 of flaring member 46 flares the end of the outer conductive sheath away from the insulation means. Flaring member 46 is replaced with expanding member 54, and upon movable jaw member 2 being moved towards stationary jaw member 1 via driving screw 5, projection 51 moves within the flared portion of the outer conductive sheath. Jaw member 2 is moved toward jaw member 1 until the outer conductive sheath engages the fiat surface of the expanding insert adjacent the inner end of projection 51. The end of other piece of cable means is also flared and expanded in the same manner as described hereinabove.

The chuck means and expanding member 54 are removed from the jaw members and a pusher member 5-5 is inserted within a respective jaw member Without being presently secured therein via locking members 2 5 and the U-shaped recesses of the pusher members are disposed in communication with openings 23'. A center contact (not shown) is inserted into one of the pieces of cable means into engagement with the center conductor and a sleeve member (not shown) has about half its length inserted in the expanded portion of the outer conductive sheath. The end of the other piece of cable means is pushed onto the sleeve so that the sleeve is disposed in the flared portion of this piece of cable and the center contact engages the center conductor thereof. The flared ends of the coaxial cable means are now in or nearly in engagement.

Loading rings 68 are pushed against the flared portions of the cable means and the partially terminated cable means is inserted within pusher member 55 of Tool T as illustrated in FIGURE 13. Bolt 63 is disposed within opening 23' and the bottom surfaces of extensions 64 engage the cable means, the loading rings and flared portions of the cable means being disposed between extensions '64 as illustrated in FIGURE 14. The top surface of bolt 63 on each side of extension '65 completes the circular configuration of the exterior surfaces of pusher members 55 and the sides of bolt 63 engage U-shaped flange members 58. Recess 66 is disposed in alignment with groove 57 of the corresponding pusher member. Handle 67 is rotated in one or the other directions causing bolt 63 and pusher members 55 to be correspondingly rotated which locks the cable means within the jaw members of the tool as illustrated in FIGURES and 16. Locking members 25 in jaw member 1 are moved into locking position within groove 57 of the pusher member and recess 66 of bolt 63 while the locking member in jaw member 2 is moved only into groove 57 of the pusher member. After the bolt has been locked in position and prior to the movement of movable jaw 2, the portion of extension 65 adjacent recess 66 in bolt 63 is disposed within recess 23 of jaw member 1 while the opposite edge portion of extension 65 is spaced from recess 23 in jaw member 2 because Tool T has not been actuated to complete the termination of the cable means.

Driving screw 5 is actuated via ratchet wrench 22 moving jaw member 2 toward jaw member 1 which causes pusher members 55 to exert pressure along a substantial portion of the outer edges of loading rings 68 thereby moving them along the flared portions of the cable means until they reach an abutting or near abutting position as illustrated in FIGURE 15 causing the loading rings to press the flared portions against the sleeve to effect an excellent mechanical and electrical connection. At this position, both ends of extension 65 are disposed in respective recesses 23 of the jaw members thereby preventing these loading rings from being driven too far by the pusher members. Since the driving force exerted on the ends of loading rings via the pusher members is opposite from the location of bolt 63, the inside surface of this bolt acts on a guide means to guide the movement of the loaded rings toward each other, the bolt prevents the termination from being buckled during this movement and the ends of extension 65 act as a stop means to prevent the movable jaw member from being moved any further than the required amount to affect the termination. After the termination has been effected, the locking screws are loosened, bolt 63 is moved to the position illustrated in FIGURE 14 and it and the terminated cable means are removed from the tool.

The present invention can be used to apply a jack and plug fitting of the type illustrated in FIGURE 14 of Ser. No. 315,787. A piece of cable means is secured within the chuck means and a loading ring 68 is placed within bore 43 surrounding the end of the cable means. This can be accomplished because, as illustrated in FIG- URE 5, bore 43 of aligning member 42 is of suflicient diameter to allow the loading ring therein and the length of aligning member 42 is about the same as that of loading ring 68. Thus, the smaller end of the loading ring abutts the ends of jaw members 33 to maintain the loading ring in position during the termination of the coaxial cable means. After the end of the cable means has been flared by means of flaring members 46, the piece of cable means is left within chuck means CM. Flaring insert 50 is removed from round section 47 of flaring member 46 and holder 69 in FIGURE 17 is threadably mounted in round section 47. A jack fitting 70 is threadably mounted within the threaded section of holder 69; this holder and round section 47 are disposed within jaw member 1.

Jack fitting 70 is threadably mounted within the threaded section of holder 69 and upon rotation of driving screw 5, jack fitting 70 is applied to the flared portion of the coaxial cable means thereby causing the outer conductive sheath to be loaded against loading ring 68 and secured therein to provide an efiective termination. Bore 43 of aligning member 42 serves to prevent the loading ring from being over-stressed. The terminated cable means is removed from the chuck means and another piece of cable means is placed within the chuck means. After the loading ring has been placed on the end of the cable means within bore 43 and the flaring and expanding operations have been performed on the end of the cable means, holder 71 having nut 72 and plug fitting 73 threadably mounted thereon is threadably mounted in round section 47 and applied to the flared portion of the cable means in the same manner as described hereinbefore. This terminated cable means is also removed from the chuck means. Alternatively, the loading ring may be applied to a flared and expanded end of a coaxial cable means by using a single pusher member 55 instead of the chuck means in combination with a holder 69 and jack fitting 70 or a holder 71, nut 72 and plug fitting 73. Of course, a bolt similar to bolt 63 is used in order to lock the cable means within the jaw member and to act as a stop to obtain optimum placement of the loading ring.

FIGURES 19 through 21 illustrate an alternative Tool T having rail members 3' provided with block member 4 connecting the ends of the rail members together opposite stationary jaw member 1'. Block member 4 has a bore 74 extending therethrough which is in communication with threaded section 75 of larger diameter at the outer end. A round stepped section 76 extends outwardly from the inner end of block member 4' and is mateable 7 with a correspondingly shaped opening 77 and extension 8 of jaw member 2. The inner end of bore 74 has an aperture 78 of smaller diameter than bore 74.

A piston shaft 79 is disposed in aperture 78 and bore 74 and has one end connected to the inner end of opening 77 via screw member 80. The other end of piston shaft 79 defines a piston head 81 which has a diameter about equal to that of bore 74. A circumferential groove 82 is disposed in piston head 81 and an O-ring 83 is disposed therein to provide a seal between piston head 81 and bore 74. A plug 84 is threadably disposed in threaded section 75 and has an opening 85 extending therethrough for communication with bore 74. An O-ring 86 is disposed in an annular recess 87 of threaded section 75 in order to provide a seal between plug 84 and threaded section 75.

A fitting 88 is threadably disposed in opening 85 and this fitting is connected to a source of fluid (not shown) in order to drive the piston head and shaft thereby moving movable jaw member 2 relative to stationary jaw member 1' against the bias of coil spring 89 which surrounds piston shaft 79 between piston head 81 and the inner end of bore 74. This coil spring maintains movable. jaw member 2 in a normally inoperative position as illustrated in FIGURE 20. Thus, as can be discerned, the tool of FIGURES 19 through 21 is similar to that of the tool described hereinabove except that the tool in FIGURES 19 through 21 is fluid operated whereas the tool described in FIGURES 1 through 3 is operated via a driving screw. Of course, other driving means to move movable jaw member relative to stationary jaw member 1 can be utilized if desired. While the tool of the present invention has been disclosed in conjunction with the handle means, it is obvious that the tool can be mounted on a bench or used in any other suitable manner to accomplish the intended result.

In view of the foregoing, there has been disclosed a unique tool to apply connection means to tubular means, such as for example coaxial cable means, wherein various removable insertable means can be utilized to perform various operations upon the tubular means in order to accomplish the intended result of terminating the coaxial cable means.

It will, therefore, be appreciated that the aforementioned and other desirable objects have been achieved; however, it should be emphasized that the particular embodiments of the invention, which are shown and described herein, are intended as merely illustrative and not as restrictive of the invention.
